Venous stents for post-EVAR graft limb kinking: two case reports.

ObjectivesTo assess dedicated venous stents' feasibility and early outcomes as a post-EVAR graft limb kinking treatment.MethodsWe report two clinical cases of severe graft limb kinking detected 1 year after EVAR.ResultsBoth patients were successfully treated with dedicated venous stents and experienced no further aortic-related events during follow-up. Graft limb kinking is a common EVAR complication, particularly in anatomically complex cases involving iliac tortuosity. Current literature emphasises the evaluation of graft-related complications but lacks recommendations for preemptive stenting or standardised management.ConclusionsOur findings highlight the potential of venous stents' adaptability to challenging anatomy vessels. Venous stents' flexibility and high radial force may reduce early occlusion rates. Further research is needed to compare the outcomes of dedicated venous stents with bare-metal stents and to optimise prevention and treatment strategies for post-EVAR graft limb kinking.
